Question about 1994 GMC Sierra
The panel lights are out and the fuse blow instantly, unplugged the ac under the hood, nothing changed. nothigng works and its cold out. any clues to check????
Start with the obvious... you have a short circuit... i presume the fuse you have to keep replacing controls the fan. look under the dash near the fan and look for the resister block that controls the fan... you won't see the actual resisters but you will see wires that plug into the side of the duct work for the vents.... remove the two screws holding that block in and check the condition of the resister block. while you have the part out and unplugged you can easily test if the short is there by putting to fuse back in and seeing if it blows again.
